See pinyl. IMG:content-0214.jpg:[blocks in formation] breech-loading guns, invented by Lefaucheux in 1836. Within a rece of the metal base of the cartridge, whose body is of paper, is placed a percu ion-cap, the open end of which faces a hole in the side of the base. Into this hole is loosely fitted a bra firing-pin, which penetrates the cap, and, when the cartridge is placed in the gun and the breech closed, projects through a small hole or rece in the barrel. The hammer of the lock strikes the outer end of this pin in firing, driving the pin down upon and igniting the detonating material in the cap. This cartridge is considered the parent of the modern central-fire and rim-fire cartridges. 2.
